How to Assemble an Earth Harp

For the past week, the avant-garde troupe MASS Ensemble has been in residence at UAB's Alys Stephens Center, offering free public mini-concerts to show off the group's intriguing Earth Harp, a complex creation that turns buildings into instruments through a series of brass "strings," tuning blocks, and resonators. MASS members tapped UAB engineering students to help them install the Earth Harp on Monday, in an hours-long sequence captured by UAB photographer Steve Wood in this time-lapse film.
